Magmatic Controls on Metal Endowments of Porphyry Cu-Au Deposits

, 2021
This overview illustrates the processes controlling magma fertility in the formation of porphyry Cu-Au deposits. Magma fertility means all magmatic parameters (e.g., metal and volatile contents, magma and fluid volumes) that might result in higher ...

Determination of geospatial criteria and prediction of potential areas for porphyry copper deposits in Kazakhstan

Frontiers in Earth Science
Determining spatial parameters related to mineral deposits is crucial for analysing mineral prospectivity. These spatial parameters, called Geospatial Criteria (GC), can serve as input data for modelling mineral prospectivity.

Temporal relations between mineral deposits and global tectonic cycles

, 2013
Natural Environment Research Council (grant NE/J021822/1) supported this research.Mineral deposits are heterogeneously distributed in both space and time, with variations reflecting tectonic setting, evolving environmental conditions, as in the ...

Porphyry indicator zircons (PIZs): Application to exploration of porphyry copper deposits

Ore Geology Reviews, 2020
Abstract Magmas with a high oxidation state (FMQ +1 to +2), a high-water content (≥ 4 wt % H2O) and a high degree of fractionation are necessary to form porphyry copper deposits (PCDs). Different proxies, such as Fe3+/Fe2+ ratio of whole-rock, minerals indicative of high oxygen fugacity (fO2) and water content as well as geochemical signatures of ...

Characteristics of Micas from Sericitolite of the Gongpoquan and Baishantang Deposits, Beishan Area by Scanning Electron Microscope, X-ray Diffraction and Electron Microprobe Analyses

Yankuang ceshi, 2016
The phyllic alteration zone is regarded as one of the most important near-surface markers in mineral exploration of porphyry deposits. The Gongpoquan and Baishantang copper deposits are two typical porphyry deposits in the Beishan metallogenic belt.

Oxidized sulfur-rich arc magmas formed porphyry Cu deposits by 1.88 Ga

Nature Communications, 2021
Tectonomagmatic conditions in the Precambrian were hypothesized to be unfavorable for porphyry Cu deposit formation. Here, the authors show that metallogenic processes typify Phanerozoic porphyry Cu deposits operated by ~1.88 Ga, reflecting modification ...

Decoupling of Sr-Nd Isotopic Composition Induced by Potassic Alteration in the Shapinggou Porphyry Mo Deposit of the Qinling–Dabie Orogenic Belt, China

, 2021
In our previous study on petrogenesis of quartz syenite and granite porphyry, the host rocks of the Late Mesozoic Shapinggou Mo deposit in the Qinling–Dabie orogenic belt, we found that the initial Sr isotopic composition of the host rocks is strongly ...

Controls on the formation of porphyry Mo deposits: Insights from porphyry (-skarn) Mo deposits in northeastern China

American Mineralogist, 2022
AbstractPorphyry Mo deposits have traditionally been classified into two major classes, arc-related and Climax-type, based on the tectonic setting and chemistry of associated intrusions. Although there is a consensus that porphyry Mo systems were formed by the optimal coincidence of geological processes operating at different scales, it is unclear what

Early cretaceous molybdenum-bearing felsic magmatic rocks in the tongmushan district, northern great Xing’an range: implications for mesozoic porphyry metallogenesis

Frontiers in Earth Science
The Nenjiang-Heihe metallogenic belt of the northern Great Xing’an Range is renowned for Mesozoic epithermal Au deposits, however, apart from the Duobaoshan and Tongshan super-large porphyry deposits in the Paleozoic, no superlarge porphyry copper ...
